DA14531 - add features to prox reporter example

Hi Stanly,

Thank you for posting your question online.

it should bond with only one device (to store the MAC ID 1st time)

Please refer on the DA1453x Tutorial BLE Security — DA1453x&DA1458x Tutorial BLE security (renesas.com)
Please also check the ble_app_security example.

• it should pair with that device (when the mac ID matches)
• no other device should not be connected in between or bonded with the device

You can either use Directed Advertising (set the Bluetooth Address a.k.a. MAC ID of the Central device so it is the only device that can see the Advertising packets) or Whitelist the device that you want to be able to send a connection request.
Please refer on the following:
1) DA1453x / DA1458x Tutorial BLE Advertising — DA145XX Tutorial BLE Advertising (renesas.com) and here: 4. User Guides — DA14585/DA14531 SW Platform Reference Manual (renesas.com) for the Directed Advertising concept

i have tried to add the function to allow the particular device to connect but it has some errors like

param->peer_addr.addr (this thing changes when the device is reset) if i fix that random address it connects and disconnect properly but when another device tries to connect it 

the device stops working and holds at ASSERT_ERROR (0).

how can i get the MAC Address of the device tries to connect

and if other device try to connect it should reject it and start the process again

Hi Stanly,

Thank you for the reply and apologies for the delay.
I can see that you have made some modifications on the gapc_connection_req_ind_handler which is part of the SDK files.
We highly recommend you do NOT modify the SDK files unless absolutely necessary. We can not support SDK customizations.
You should able to create your application on the user folders:

If you are not using Whitelisting or Directed advertising, then the only think you can do is to check on the connection handler:

    .app_on_connection                  = user_app_connection,

Check the Central BDA upon connection and reject any connections that is not from your central.
Another approach would be to implement Passkey Security so any device that does not know the Passkey will not be able to connect.

prox_reporter_531.hex 

can i get the power profile of the hex file (in pairing and advertising)

and please help me in how to turn off all sleep mode in the prox reporter in the SDK 6

and how to remove the unwanted services which provided in prox reporter after pairing 

 Advertising data length - maximum 28 bytes, 3 bytes are reserved 

Hi Stanly,

Thank you for the reply.
Please find below the video showcasing the Hex you provided during advertise and connection. There was no security request sent so no Pairing/Bonding procedure was initiated.

Please refer on the: DA1453x & DA1458x Sleep Modes Tutorial — DA1453x & DA1458x Tutorial Sleep Modes (renesas.com)
On the user_proxr.h file you can undefine the Deep Sleep and Hibernation Sleep macros so they will not take effect in your project.

Please go through the documentation. Everything is explained in the Documents.
